Front

What is the probability of selecting a blue marble if there are 5 blue marbles and 15 total marbles?

Back

The probability is 5/15 or 1/3, which is approximately 33.33%.

What is the formula for the surface area of a rectangular prism?

Back

Surface Area = 2(lw + lh + wh), where l = length, w = width, h = height.

Front

Calculate the surface area of a rectangular prism with length 6 cm, width 4 cm, and height 10 cm.

Back

Surface Area = 2(6*4 + 6*10 + 4*10) = 2(24 + 60 + 40) = 2(124) = 248 cm².

Front

What is the formula for the circumference of a circle?

Back

Circumference = πd, where d is the diameter.

Front

If the diameter of a circle is 10 cm, what is its circumference?

Back

Circumference = π * 10 ≈ 31.42 cm.

Front

What is a quadrilateral?

Front

Name the types of quadrilaterals.

Back

Types include squares, rectangles, rhombuses, parallelograms, trapezoids, and kites.
